The rate of blinking increases when you're talking, when you're nervous, in pain, or when you're exposed to very bright lights. Frequent blinking may also occur as a nervous tic in some people.
For instance, studies have shown that we blink more when we are experiencing a high cognitive load than when our brains are not being taxed. Also, researchers examining brain activity in relation to blink rate have concluded that a high blink rate can signify a disengagement of attention.
Did you know that when someone is attracted to you, their blink rate can increase significantly? This is because the number of times we blink is linked to emotional excitement.

The average person blinks some 15-20 times per minute—so frequently that our eyes are closed for roughly 10% of our waking hours overall.
The average frequency of blinks per minute ( min) among the women was 23.81 blinks per min, and among the men was 31.67 blinks per min ( p= 0.002) . The average duration of each blink in women was 0.51 seconds ( s) and in men was 0.26s ( p= 0.009) .
Results: Spontaneous blink rate was significantly larger in women than in men (19 vs 11 blinks per minute); older women blinked more frequently than younger women.
It has been reported that the normal spontaneous blink rate is between 12 and 15/min. Other studies showed that the interval between blinks ranges from 2.8 to 4 and from 2 to 10 s. A mean blink rate of up to 22 blinks/min has been reported under relaxed conditions.

Excessive blinking isn't usually connected to a serious health condition. In this case, it may go away on its own without treatment. If you need treatment, the options depend on the cause.
Nakano and her colleagues found that when we blink while paying attention to a task, we're resetting our brain. Think of it like rebooting your computer. When we engage in a task, such watching a movie, our brain's attention networks are triggered.
The flow of visual information to the brain is halted by up to 450 milliseconds with every blink, and we lose up to 6 seconds of information every minute, says Tamani Nakano at the University of Tokyo in Japan.
Blinking cleans the ocular surface of debris and flushes fresh tears over the ocular surface. Each blink brings nutrients to the eye surface structures keeping them healthy. The flow of tears is responsible for wetting the lower third of the cornea.
When you are under stress, you may become more sensitive to light and eye strain. General health conditions that may cause an increase in eye blinking include: anxiety. stress.
